K the .valve which is a piston valve, and which is provided with a' circumferential groove or chamber is and a valve spindle 7a. The-piston valve is arranged in a cylindrical valve chamber or sleeve Lwhioh is secured in the valve chest. The piston valve and its sleeve are formed of hardened metal, and they-are ground together so that they work with very little friction and do not wear away quickly. I r p T he sleeveL is conical or plug-shaped ex tern-ally, and m is an adjusting and fastening screw which engages with. a screw threaded hole in a covermtwhich is bolted to one end of thevalve chest. The screw m has a bearing a which is journaled in a bar 12 formed on one end of the sleeve L. The sleeve is held per ianently in position by the screw which forces itinto steam-tight 1'elation \\'itl1 its tapering socketin the valve chest. v

The valve spindle 7; projects through a stutling-hox 7) on the valve chest, and? is a link which is pivoted by a pin q to an eye q on the outer endot the valve spindle. The link P is pivoted. to the "frame A by a i sliding.longitudinally but permits it to move laterally with the cylinder when the cylilr der is oscillated on its trunnions.

The valve chest is provided with a chamber 2 which encircles the middle part of the l sleeve L, and the sleeve isprovided with a Patented May 7, 1912.

- formed in the valve chest around the sleeve manner by means of a passage 13 terminather 9, port 10, past .one end of the piston frame, and a crankshaft journaled therein;

' The chamber 7 is connected with one end steam is admitted to and exhausted from thesis on the valve.

said frame and operatively connected with the crankshaft, a valve-chest secured crosspiston-valve arranged in the said valve port or ports 3 which communicate with this chamber. The chamber 2 is connected with the chamber G by means of a passage 4 formed in the wall of the cylinder and valve chest. I

The valve chest is provided with two chambers 5 at the ends of the sleeve L, and these chambers 5 are connected together and to the chamber H by means of a passage 6, alsoformed in the wall of the cylinder and Two annular chambers and 9 are L and are arranged one on each side of the middle chamber 2. The sleeve'is provided with ports 8 and 10 in its side which communicate with the chambers 7 and 9 respectively.

of the cylinder by apassage 11 terminating in a cylinder port 12 as shown in Figs. 3 and 4. The chambir. t is connected with the other endof the cylinder in a similar valve into the chamber 5, and thence by passage 6 and chamber H into the exhaust pipe 71.. The rotary motion of the crank oscillates the cylinder on its trunnions, and the valve chest-is reciprocated upon the piston valve, said piston valve being retained in position by the link P which only permits it to have motion laterally to accomniodate' itself to the curvature of the are on which it moves with the valve chest. The

the opposite ends of the cylinder alternately by the longitudinal motion of the valve What I "claim is: i 1. The combination, with a stationar of an --oscillatory cylinder pivoted to the Wise o' f'the axis of the cylinder and having a cylindrical valve chamber arranged to oscillate longitudinally upon the same pivot as the cylinder, a substantially stationary chamber, and means for preventing the said valve from moving longitudinally, the said valve chamber, chest, valve and cylinder being provided with passages for admission and exhaust, and the said valve chamber being adapted to reciprocate longitudinally upon the said valve.

2. The combination, with a stationary frame, and'a crankshaft journaled therein;

of an oscillatory cylinder pivoted to the said frame and operatively connected with the crankshaft, a valve-chest secured crosswise of the axis of the cylinder and having a cylindrical valve chamber arranged to es cilla-te longitudinally upon the same pivot as the cylinder, a substantially stationary piston-valve arranged in the said valve chamber and provided with a spindle which projects from the valve-chest, and a link pivoted to. the projecting end portion of the valve spindle and to the stationary frame, the; said valve chamber being adapted to reciprocate longitudinally upon the said valve, and the said valvechamber, chest,

valve and cylinder-being provided with passages for admission and exhaust.

' 3. The combination, with a cylinder providedwith a valve chest having a tapering socket, of a plate having a'screwthreaded hole and secured to one end of the valve chest, asleeve tapered externally to fit the'socket and provided with a bar extending across one end of it, a valve workin in the said sleeve, and a fastening screw or the sleeve engaging with the said plate and provided with a bearing which is journaled in the said bar upon the axis of the sleeve, said screw also affording a means for extracting the sleeve from the socket.

4. The combination, with a stationary frame, and a crankshaft journaled therein; of an oscillatory cylinder pivoted to the said frame and operatively connected with the crankshaft, a valve-chest secured crosswise of the axis of the'cylinder and having a valve chamber arranged to oscillate longitudinally upon the same pivot as the cylinder, a substantially stationary valve ar ranged in the said chamber, and means for preventing the said valve from moving longitudinally, the said valve chamber, chest, valve and cylinder being provided with passages for'admission and exhaust. and the said valve chamber being adapted to reciprocate longitudinally over the said valve.

In testimony whereof I-havc affixed my signature in the presence of two witnesses.
